Specification of Letters Patent.

Patented D6... 22, 1914.

Application filed February 26,1914. Serial no. 821,228.

To all whom it may concern:

Be it known that I, WARD C. WALKER, a citizen of the United States, residing at Battle Creek, Michigan, have invented certain new and useful Improvements in Hose- Clamps, of which the following is a specification. v

This invention relates to improvements in hose clamps.

The main objects of this invention are: First, to provide an improved hose clamp of the nut and bolt tpye which is very efiicient and very economical, even when made of large sizes. Second, to provide an improved hose clamp of the nut and bolttype in which the body of the clamp is formed of a single piece of wire.

Further objects, and objects relating to details of construction and operation will definitel appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. 1

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is. a detail elevation of a hose clamp embodying the features of my invention mounted upon a piece of hose. Fig. II is an enlarged detail section on a line corresponding to line 2-2 of Fig. 1. Fig. Ill is a detail section on a line corresponding to line 3-3 of .Fig. IL Fig. IV is a detail section on a line corresponding to line of Fig. II. Fig. V is a detail side elevation of my improved clamp mounted upon a piece of hose, the hose being shown in section. Fig. VI is a detail side elevation of a slightly-modified form of my invention. Fig. VII is a detail section on a line corresponding to line 7-7 of Fig. VI.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in thedirection of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents a piece of hose and 2 a hose coupling member to which the hose is connected by one of my improved clamps. In the preferred embodiment of my invention the clamp comprises an integralbody member formed of wire folded into a loop providing spaced band members 3 having a coil 4 at the loop end, the coil being disposed "outwardly and constituting an eye for the clamping bolt 5. The band members have coils 6 adjacent their other ends, the coils being disposed T OFFICE,

outwardly and side by side and constituting bolt eyes for the clamping bolt 5. The coils 6 are preferably welded together; as indicated at 7, so that they are held in the proper relation when the bolt is removed. The ends of the band members are extended beyond the coil 6 to provide joint lap members or tongues 8. These joint lap members or tongues 8 are disposed substantially parallel with the band members 3 and lie between the band members and below the bolt coil or eye 4 whereby they are retained in position and supported.

The ends of the coils 6 are brought around so that they contact at 9 and are preferably welded at that point, as indicated. This reinforces and stifl'ens the joint tongues or joint lap members, that is, it prevents their springing up at this point under the stress of drawing up the clamp or of the strain from within the hose. The joint tongues or lap members, with the parts thus arranged. form with the band members a continuous contact about the hose.

The nut 10 of the bolt engages the band members so that it is prevented from turning,the bolt being preferably what is commonly designated as a stove bolt, and provided with a head slotted to receive a screw driver.

My improved clamp is very eiiicient, being capable of withstanding very heavy strains and clamps the hose upon the coupling very securely accommodating itself to any irregu larity of the parts. The structure is very economical to produce, even when made of large sizes. and is well adapted for clamps of large dimensions. A further advantage is that there are noprojecting or rough corners. which is a very desirable fieature.

In Figs. VI and VII I illustrate a slightly modified form of my invention, the ends of thebolt eye coils 11 being brought underthe band members at 12 instead of in front of the same. This clamps the lap joint, extensions or tongues 8 firmly upon the hose at this point.

lates to embody or adapt the same as may be desired. I desire, however, to be understood as claiming my improvements specifically in the form illustrated as Well as broadly within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is: v

1. A hose clamp comprising an integral body formed of wire folded into a loop providing spaced band members and having a coil at the loop end disposedoutwardly and constituting a bolt eye, the band members having coils adjacent their other ends disposed outwardly side by side and constituting bolt eyes, the ends of the eye coils being welded and the eyes being welded together, the ends of the said band members being extended beyond said eye coils and constituting joint lap members, said joint lap members being disposed between the band members and below the bolt eye at the loop end of the body whereby they are retained in position and supported, and a bolt through said eyes.

2. A hose clamp comprising an integral body formed of wire folded into a loop providing spaced band members and having a coil at the loop end disposed outwardly and constituting a bolt eye, the band members having coils adjacent their other ends disposed outwardly side by side and constituting bolt eyes, the ends of the eye coils being welded and the eyes being welded together, the ends of the said band members being extended beyond said eye coils and constituting joint lap members, and a bolt through said eyes. I

3. A hose clamp comprising an integral body formed of wire folded into a loop providing spaced band members and having a coil at the loop end disposed outwardly and constituting-a bolt eye, the band members having coils adjace t their other ends dis-- posed outwardly si e by side and constitute ing bolt eyes, the eyes being welded together, the ends of the said band members being extended beyond said eye coils and constituting joint. lap members, said joint lap members being disposed between the band members and below the bolt eye at the loop end of the body whereby they are retained in position and supported, and a bolt through said eyes.

4. hose clamp comprising an integral body formed of wire folded into a loop providing spaced band members and having a coil at the loop end disposed outwardly and constituting a bolt eye, the band members having coilsadjacent their other ends dis-.

osed outwardly side ,by side and constitutmg bolt eyes, the eyes being welded tosaid band members being extended beyond said eye coils and constituting joint lap members, said joint lap members being disposed between the band members and'below the bolt eye at the loop end of the body so that they are retained and supported in position thereby, and a bolt through said eyes.

6. A hose clamp comprising a body formed of wire folded into a loop providing spaced band members and having a coil at the loop and constituting a bolt eye, the band members having coils adjacent their other ends disposed outwardly and side by side and constituting bolt eyes, the ends of said band members being extended beyond said eye coils, and constituting joint lap members, and a bolt through said eyes.

'7. A hose clamp comprising bandmembers of wire having coils adjacent one end thereof disposed-side by side and constitutingbolt eyes, the ends of the coils being welded and the eyes being welded together, the ends of said members being extended beyond the said eye coils and constituting joint lap members, and a clamping bolt, the other ends of said band members being provided with a coacting eye.

8. A hose clamp comprising band members of wire having coils adjacent one end thereof disposed side by side and constituting bolt eyes, the eyes being welded together, the ends of said members being extended beyond the said eye coils and constituting joint lap members, and a clamping bolt, the other ends of said band members being provided with a coacting eye.

9. A hose clamp comprising band members of wire having coils adjacent one end thereof disposed side by side and constituting bolt eyes, the ends of said members being extended beyond the said eye coils and constituting joint lap members, and a clamping bolt, the otherends of said band members being provided with a coacting eye.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
